Copper 101 & 102 Alloys

Did you know?

Copper 101 Alloy — It is commonly used in the telecommunications industry and plays an important role in our economy. Being a electronic grade alloy alloy, it’s an excellent conductor of heat and electricity. While it was once used in coins and even in home decorations, today it’s more commonly applied to roofing. It’s also found in electronic conductors and glass to metal seals.

It has excellent conductivity and malleability. Not to mention, it’s corrosion resistant and can easily be combined with nickel, zinc, and aluminum. Copper can easily be recycled. Old pipes, taps, and car radiators made out of Copper can be melted down and reused without losing any properties. It has an excellent capacity for being both cold worked and hot formed.

Similar to Copper 101, Copper 102 is also used in the telecommunications industry and has high electrical resistivity/conductivity. It has an excellent capacity for being cold worked and hot formed. It has high ductility and high electrical and thermal conductivity. Not to mention, Copper 102 can be easily welded and is strong (has high impact strength). A few applications include: glass to metal seals, electronic conductors, and vacuum tubes. Copper 102 has low temperature properties and as its temperature decreases, its strength increases.
